In February 2011, Eric Sherred was feeling good.
The Republican had just landed a new assignment: working on Rick Santorum's presidential campaign as a digital strategist.
One of his main responsibilities would be search engine optimization. That is, making sure the campaign's website turned up high in Google searches.
So, Sherred was pretty happy.
That is, until he went home, turned on Comedy Central, and saw Stephen Colbert urge people to Google Rick Santorum.
